Idris Elba has called for greater diversity in the media - both in front of and behind the camera - in an address to MPs in Parliament.

The Luther star urged better representation of women, disabled people and people of different races.

Speaking of how many actors decide to work abroad, he described the American Dream as "the most famous diversity policy of all."

"The problem is the gap between the dream and reality."

However, Mr Brokenshire goes on to make clear that the US is the UK's most important bilateral ally and that it is the responsibility of the UK to engage with all its presidential candidates, even when we profoundly disagree with their views. The answer is to engage in "robust democratic debate". With that the debate comes to an end. The MPs agree that they have duly considered the petition and the issue in hand but do not hold a vote on whether to ban Mr Trump. 

Home Office minister James Brokenshire concludes the debate on Donald Trump by criticising the tycoon's call for a ban on Muslims, saying he could "not be further from the truth". Anyone who "gives succour to the false view that Muslims cannot live a purposeful and fulfilled life in the West" must be challenged, he adds, saying there are millions of UK citizens who believe there is no contradiction in being a "proud Muslim and a proud Briton". He says the home secretary takes a decision on whether to exclude someone on a case-by-case basis, taking into account the "available evidence" and a "wide range of policy and operational factors". In the past, he points out, banning orders have been imposed against "those who seek to do us harm" and to incite "hatred and violence" whatever their origin.  

SNP MP Anne McLaughlin concludes her appeal for Donald Trump to be banned by quoting the former civil rights leader Martin Luther King, whose birthday is being marked by an annual public holiday in the US today.

Away from the Donald Trump debate, it is being widely reported that Labour MP Steve Rotheram is set to be voted off the party's National Executive Committee after becoming a ministerial aide to Jeremy Corbyn. It is being interpreted as another skirmish between the Labour leader and MPs concerned about the direction of the party.

Tory MP Kwasi Kwarteng says that banning Donald Trump is likely to help his chance of winning the Republican nomination and potentially becoming president. To those who argue that Mr Trump has no chance of making it to the White House, Mr Kwarteng says "look at the odds of Jeremy Corbyn becoming Labour leader". A ban, he concludes, would "play into Mr Trump's hands" and "reignite all the publicity he has generated from his outrageous policy". Fellow Conservative Sarah Wollaston takes a different view, saying a ban would have no impact on the presidential race but would "send a very clear message to the people of the United States about what we feel about those who demonise an entire people for no other reason apart from their religion". That said, she says the likelihood of it happening is very small. 

Earlier on Monday, Green Party leader Natalie Bennett and UKIP MEP David Coburn discussed calls to ban Donald Trump from the UK on the BBC's Daily Politics programme. Listen to their exchanges.

The 'Ban Trump' petition states that the UK "has banned entry to many individuals for hate speech" and argues that the rules must be "fairly applied to the rich as well as poor".

A counter-petition argues that foreign nationals should not be banned "for their opinions on domestic actions" and that a ban would risk damaging US-UK relations given the possibility of a Trump victory in November's election.

MPs are continuing to debate a petition, which has attracted 574,000 signatures, urging the government to ban Donald Trump from the UK, after his call for all Muslims to be denied entry to the US.

The debate is scheduled to finish at 19:30 BST. We'll continue to bring you updates on what MPs are saying.

Who is banned from the UK already?

Home affairs correspondent Danny Shaw spoke to PM presenter Eddie Mair about what the government criteria are for banning someone from the UK, and who has been banned to date.

Westminster Hall

Conservative MP Steve Double, a member of the Petitions Committee, says he condemns "wholeheartedly" Donald Trump's comments. But he says the UK has a long and strong tradition of free speech, and it is not right to ban him on the basis of disagreeing with what he has to say.

"There are many people who have equally intolerant views", including British citizens, so are they to be banned too just because we disagree with them, he asks.

He adds that Mr Trump has not crossed the line to incite violence or criminal acts.

SNP MP Tasmina Ahmed-Sheikh says Mr Trump's comments "condemn a whole religion for the actions of a terrorist death cult".

She says he's also been offensive about women, Mexicans and people with disabilities.

His comments are "dangerous and his view must be tackled seriously", she adds.

Endorsing a ban, she says the home secretary should enact the powers she has to block his entry.

Donald Trump is "no more than a demagogue", says Naz Shah, the Labour MP for Bradford West.

"He panders to people's fears as opposed to their strengths," she tells MPs, but adds that she would invite the tycoon to visit her constituency to show him why she thinks what he's said is wrong.

"Liberty is not something we can take in caution or in part", says Conservative MP Tom Tugendhat.

He says it is for the American people to judge Trump and hold him to account. 

"It is bad politics and judgement to intervene in the electoral process of other countries," he adds.

While he thinks Trump is "crazy" and has "no valid points" to make, "I will not be the one to silence his voice", he tells the room.

Acknowledging that today is Martin Luther King Day, Mr Tugendhat points out that the civil rights leader relied on rights of freedom when he was campaigning for desegregation.

Donald Trump called for a temporary ban on all Muslims entering the US in response to the shooting of 14 people in San Bernardino, California in December.

The tycoon's comments were criticised across the political spectrum in the US and Europe.

He caused further anger by claiming that areas of London and other parts of the UK have become so radicalised that they have become no-go areas for the police.
